Description

The Sentinel boasts a 3 star (Hubbel's guide) trad route called Crooked Cross. 5 other trad routes are listed for the rock, and there is a seemingly new bolted line around the corner to the left of the first route, Spy Story. Some of the rock looks iffy, but Crooked Cross is clean and well worth doing. It has an easy walk off the top.

Getting There

4.5 miles from the light at the junction of US 36 and CO 7 (Hubbel). There's a pulloff next to the river, and an easy low water crossing. You can't miss the Crooked Cross Crack high above you. Poison ivy is out there, but it didn't seem too bad. The quasi trail heads up to the right of Crooked Cross.

During high water the normal crossing (straight below the climb) is swift and deep. It is easier to cross at a wide spot a couple hundred yards upstream, then endure a thrashing through poison ivy and battle up a rising traverse on steep grassy slopes to the base of the routes. At least you won't have to wait in line! Jun 28, 2004

Crossing directly below the formation was easy on 4/29/2018 when streamflow was at 80 cfs. For daily data: dwr.state.co.us/SurfaceWate…,

Look for SVCLOCO (St. Vrain Creek, Lyons, CO), which I guess is closest measure to The Sentinel. Apr 30, 2018
